It occurs to me that I don’t know of any accident where cutting along the dotted line was both necessary and possible.
Has anyone ever seen it done?

We have tried this with the standard issue fire axe ,,,nigh on impossible ,,even if you get through the outer skin you have hatbins and interior trim to contend with,,even with a petrol cutter in the mayhem of possible leaking fuel and fluids this will be a risky process ,as most of you know i pull apart various airframes with a more than adequate machine and even this struggles sometimes,,
